0.56 Ct. Greenish Blue Sapphire from Madagascar

This 0.56 carat cushion shape sapphire presents a finely balanced greenish blue hue, originating from Madagascar and heat treated to optimize tone and uniformity. The gem measures 5.07 by 3.75 by 3.21 millimeters, a proportion that yields a compact yet substantial visual presence when mounted. Color grading identifies a medium light intensity, which in combination with the green blue hue produces a lively, cool palette that shifts subtly with viewing angle. Clarity has been evaluated as very slightly included at eye level, indicating that the stone retains transparent body color and strong windowing, while minor internal features remain inconspicuous to unaided inspection. The combination of modest size, lucid clarity, and medium light tone results in a gem that reads larger than its weight might suggest, particularly in settings that maximize face up area and light return.

The cutting style is a mixed brilliant cut, a deliberate configuration that merges brilliant crown faceting with a structured pavilion to enhance both scintillation and depth. The crown demonstrates smaller star and kite facets that break light into a lively pattern, while the pavilion uses a series of chevron and main facets to channel light back through the table for contrast and dispersion. This faceting strategy is especially effective in medium light sapphires, because it compensates for reduced saturation by amplifying internal reflection and contrast. Excellent polish across all facet planes ensures minimal surface diffusion, preserving sharp facet junctions and strong mirror reflections. The gem’s pavilion depth and table proportion are tuned to produce a balanced return of light, so that the greenish blue tone remains vivid without appearing washed out under daylight, and without creating excessive windowing under strong direct light.

For design and setting considerations this sapphire is exceptionally well suited to a statement piece, because its dimensions and high clarity provide a clean optical canvas that interacts predictably with metal and surrounding stones. In a solitaire ring the 5.07 by 3.75 millimeter face can be emphasized by a low to mid profile prong setting that exposes the pavilion to light, or by a halo of smaller melee that increases apparent size while preserving the gem’s brilliance. In a pendant the stone will carry strong table presence and retain scintillation when suspended with an open back or a minimal bezel. The very slightly included clarity grade means that internal features will not compete with facet patterning, so designs that prioritize light throughput will deliver the most impact. Provenance from Madagascar and the transparent nature of the enhancement treatment are documented, and The Natural Sapphire Company can advise on mounting options that preserve color integrity and mechanical security. Routine care with warm soapy water and a soft brush will maintain polish and brightness, avoiding harsh chemicals and ultrasonic cleaning if inclusions are of a type that could be affected. This sapphire combines thoughtful cutting, superior polish, and a desirable greenish blue palette, making it an excellent choice for clients seeking a technically refined gem with statement making potential.
